COMPOSING, MECHANISM FOR TYPE-MACHINES.

SPECIFICATION forming part of Letters Patent No. 702,568, dated June 17, 1902.

Application filed March 6 1901. Serial No. 50,107. (No model.)

T on whom it may concern.-

Be it known that I, TOLBERT LANSTON, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain newand useful Improvements in Composing Mechanism for Type-Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying 1o drawings, forming a part of this specification, and to the figures and letters of'r'eference marked thereon.

This invention relates generically to type casting and composing machines for the pro- I 5 duction of justified lines of type according to the Lanston and analogous systems, and specifically to the keyboard or composing mechanism for producing a perforated record strip or controller for governing the casting mechzo anism. Heretofore the keyboard or composing mechanism has existed as a detached adjunct of the casting or type-making mechanism, and one of the principal objects of the present invention is to unite the functions of these two machines in a single connected mechanism. With this end in view a reor ganization and improvement has been made in the composing mechanism whereby the justification-punches, although actuated at the close of the line, as heretofore, are caused to operate upon the strip at the beginning instead of atthe end of the line and the perforated strip as it emerges from the composingmachine is conducted directly to the paperfeed or other receiving member of the controlling system pertaining to the casting-machine. In order to harmonize the working of the two mechanisms thus connected through the controlling record-strip and to prevent o accidental rupture of the latter should the speed of the casting-machine exceed that of the operator at ihe keyboard, a speed-controller is connected to the casting-machine and arranged to be operated by the record- 5 strip or keyboard mechanism so as to adjust the speed of the casting-machine to that of the operator at the keyboard whenever the available record-strip is reduced to or below a predetermined quantity and to arrest the casting-machine before a rupture of the strip and for so many punchings of the charactercan take place in the event the action 'of the keyboard is suspended while the casting-machine continues in operation.

Incidentally the invention includes a composing or keyboard mechanism embodying among other novel features a series of j ustification-punches and a paper-feed therefor separate from and located in rear of the series of character-punches and its paper-feed, both of said series of punches and the feeds therefor being controlled from. the keys; a variable actuating mechanism for the said two feedscharacter and justificationcompetent to effect a feed movement of the'paper opposite the character-punches each time a punching is performed by either series of punches and to efiect a similar feed movementopposite the j ustification-punches each time a punching is performed by the latter 7o punches as are required to advance the justifica'tion area into proper relation to the justification-punches, so that during the setting up of the line on the strip the latter will be automatically advanced to present its justification area in position to receive the justification-punches at the front instead of at the rear end of the line; a take-up or drawoif mechanism operating upon the strip to withdraw the surplus from between the two feeds resulting from the excess of motion of the character-feed as compared with the jus tification-feed, thereby restablishing the initial adjustment of the parts; a perforating attachment for forming the marginal feedingperforations; a pneumatic. lock for the indicating devices, and numerous details of construction and arrangement of parts, all ashereinafter more fully described, and pointed out in the claims. r

Similar characters designate like parts in the several figures.

The new union machine illustrated in the drawings includes as its principal elements a castingand composing mechanism of the type described in Patent No. 625,998, a new composing or keyboard mechanism, (patterned after that of Patent No. 654,115, although modified and improved in numerous particulars, as will hereinafter appear,) and a speedcontrol connection intermediate the said mechanisms, through which the perforated record-strip operates to govern the speed of the casting mechanism. For convenience of description these will be considered in the order stated.

First as to the casting mechanism. The form illustrated is typical and preferred because of its demonstrated capacity. As its general construction is well known and substantially identical with that of Patent No. 625,998, a detail description is not required. It is indicated in the drawings only by the diagrammatic representation of the bed-plate 1, air-connections 2, and paper-feed mechanism 3 in Fig. 2 and by a section of the bed-plate with paper-feed attached in Figs. 1 and 26. The only material change in this element is as to the location of the paper-feed, its air connections and driving mechanism, the first of those being changed from the rear to the front of the machine, so that the keyboard operator will be within easy reach of the galley and belt-shipping lever and can thus readily oversee the casting-machine while operating the keyboard. The pneumatic connections, as well as those for transmitting motion from the main actuating-lever 4: to the feed-actuating lever 5, must of course be modified to accord with this change in location. A competent pneumatic connection is illustrated in Figs. 1, 2, S, 9, and 10 and a mechanical substitute in Fig. 11. The first utilizes the main feed-actuating lever 4 of the machine to oscillate a valve 6, contained in a casing 7, fixed to the frame. This valve is furnished with a chamber 8 in open communication with a pressure-supply through a port 9 in the casing and two supply-ducts 10 and two exhaust-ducts 11. The casing contains two ports 12, leading to opposite ends of a cylinder 13, Fig. 1, and two exhaustports 14, one in line with each supply-port 12. hen at either extreme of its motion, one of the supply-ducts 10 will coincide with the port 12, leading to one end of cylinder 13, while the opposite end of said cylinder will be placed in open communication with its exhaust-port 14 through the duct 11. The piston within cylinder 13 is connected to the actuating-lever 5 of the paper-feed by a rod 17, as seen in Fig. 1, and thereby motion is communicated to the air-bar and feeding devices. The mechanical transmission shown in Fig. 11 contemplates the location of the cams on the ends of the driving-shafts, in which case the motion of the main actuatinglever is communicated to a bell-crank 16 or other form of lever engaging a rod 17, connected to the actuating-lever 5.

Next as to the composing or keyboard mechanism or that by which the record-strip is prepared and presented directly to the casting mechanism without having to be first reversed, as was heretofore generally the case in machines of this kind. The new recordstrip-composing mechanism or keyboard is patterned somewhat after that of Patent No. ,ll5-that is to say, it is pneumatically actuated and utilizes several of the elemental features of the prior machine, and in order to more clearly distinguish the new from the old the latter will be first briefly adverted to, after which the. modifications, additions, and improvements will be more fully described. The keyboard proper, including in that term the valved finger pieces or keys 30, Figs. 1, 2, and 3, pressure-chamber 32 and its top plate 31, containing'air-ducts, but exclud ing the two rows or lines of j ustification-keys, is identical both in construction and arrangement with that of the prior patent. The keys of each column represent type of the same width, and the different columns different widths, each column being represented by an air-duct (numbered 6 to 20, inclusive, Figs. 4 and 7) to which pressure is admitted when any of the keys is depressed. The location of individual type in each column is determined by the transverse line in which it is situated and is represented by an air-duct (lettered A to N, inclusive, and X) also controlled by the'key situated at the intersection of the line and column. The duct marked 0 is controlled by the justifying space-key alone and that marked R by the resettingkey.

The indicating devices of the prior patent are also retained. These include the reciprocating line-indicator 33, Figs. 1, 2, and 3, the rotary j ustification-chart 34, the vertically-movable pointer 35, and the units mechanism. With the exception of the actuating mechanism for the pointer and the addition of a lock for the chart-carrying devices the operating mechanism for the indicating devices is also the same and includes the series of pivoted operating-levers 36, Figs. 3 and 4, each provided with a piston working in one of a series of cylinders in block 37 and to which air is admitted from one of the ducts 6 to 20, a series of stop-bars 50, Fig. 3, one for each lever 36, acting upon a units-rack (not shown) and the holding-pawl 38 to release the units-wheel 54 and measureits advance-movement, the motor 39, Fig. 30, andmotor-rack 40 for advancing the units-wheel, the resetting-motor 41, a supplemental rack 56, carried by the motor-rack 40 in position to engage a pinion 42 in the train of gears carrying the j ustification-chart, the supplemental motor 43 for assisting the advance of the j ustificationchart, and the resetting cross-shaft 44, with its valves 45 and 46, for controlling the admission and exhaust of pressure in motor 39 and resetting-motor 41, said cross-shaft being operated in one direction by its spring 47, Fig. 14, and in the opposite direction by a motor 48, Figs. 3 and 4, to which air is admitted from duct R, Fig. 7, when the resetting-key is depressed. The actuating devices for the pointer 35, instead of being located within the inclosed base, where access is difficult, are arranged above the top plate of the frame, (see Figs. 3 and 13) and comprise a shaft 150, carrying a gear 151, in engagement with the rack on the pointer, and two relatively reversed ratchet-wheels 152 and 153. That one of the operating-levers 36 whose cylinder is connected to the space-duct 0, Fig.7, carries a rod 154, whose upper end is attached to an arm 155, pivoted upon shaft 150 and carrying a driving-pawl 156, engaging ratchet-wheel 152, and a pin 157 for engaging the tail of a stop-pawl 158, the latter engaging the other ratchet-wheel 153 and being brought into action at the end of the feeding movement of pawl 156 to arrest the advance and prevent. overthrow. This pawl 158 is normally out of contact with its ratchet-wheel and is thrown into engagement therewith only at the end of the stroke of arm 155. A holding-pawl 159 is pivoted upon the frame, with its tail above or 1 inposition to be operated upon byarod 160, the latter extending down in position to be engaged by an arm 161, Fig. 14, on the resetting cross-shaft 44, so that when the latter is moved to admit pressure to the resetting-motor the holding-pawl 159 will be withdrawn and the pointer 35 permitted to drop by gravity until it rests upon the stop 162. Another new feature of this indicating mechanism is the lock for preventing the rebound or displacement of the j ustification-indicator when the unitsra ck is reset or brought back to initial position.

Working within a cylinder in the frame is a piston 165, Figs. 30 and 31, carrying a pin 166, the latter arranged to intercept an adjustable member or nut 167, carried by the rack forming part of the supplemental motor device 43. The adjustable member 167 is provided with an incline and a retaining-surface, and the pin 166 is projected into its path by a spring, so that as the supplemental motor is retractedor the justification-chart returned to zero position the member 167 will pass the pin 166 and permit the latter to engage the retaining surface or end, thereby holding the parts against movement until the pin is withdrawn. To

effect this action, the cylinder of piston 165 is connected by a duct 168 with the interior of the cylinder of motor 39, the port 169 therein being located slightly in advance of'the port communicating with the supplemental advances it will uncover port 169 and admit pressure to raise pin 166 out of the way just before admitting pressure to the supplemental motor. Another sourceof defective action, that incident to hammering, is overcome by the application of cushion-springs 170 to op motor 43, so that as the piston of motor 39 posite ends of the supplemental motor-rack.

Itis to be noted that whereas in the prior machine the operating-levers 36 performed the double function of operating the punches as well as the indicating devices, in the present machine they are used onlyin connection with the indicating mechanism, a separate series of operating-levers 180, Figs. 4, 5, and 26, being employed for the character-punches 181, which latter, together with the cooperating die-plate, are in all material respects the same as those of the prior machine, with this exception: that they are located to one side of the keys and indicating devices and in proximity to the paper-feed of the castingmachine, as best seen in Figs. 1 and 2, and, further, that they here merely represent the location of the characters, spaces, points, &c. on the die-plate of the casting-machine and the keys of the keyboard,an en tirelyindepend ent series of punches being employed for setting the justification, as will presently appear.

The series of punches 181, hereinafter designated the character-punches, are thirtyone in number and represent the fifteen degrees of motion of the die-case in transverse planes corresponding with the fifteen columns and fifteen rows of keys on the keyboard and the justifying-space punch controlled separately by the space-key through duct 0. The pneumatic or power connections will be readily understood from Fig. 7, wherein the punch-pistons to the left of the figure are marked with characters and numerals corre spending with the ducts leading from the columns and lines of keys. From an inspection of this figure it will be seen that the ducts 6 to 20, inclusive, designating columns of keys, hence size of type, are in pneumatic communication through proper pipes or passages with the corresponding cylinders of the two sets of indicating and punch-operating levers 36 and 180 and that the justifying-space duct 0 is also in communication with its indicating and pointer-actuating operating-lever 36 and punch-operating lever 180, whereas the ducts A to N and X, which designate the lines or position in column, but not size, communicate alone with the punch-cylinders.

Above the series of character-punch-operating levers 180 is the rocking frame 182, mounted upon shaft 183 and connected to the feed-valve 184;, Figs. 4, 5, 0, and 28, for controlling the inlet and exhaust of pressure in opposite ends of the feed-cylinder 185, containing the piston on the paper-feed-operat ing rod 180, all as found in the prior machine referred to.

The machine as thus far described constitutes an operative keyboard or composing mechanism for producing character-locating perforations in the record-strip and indicating the amount of line occupied and the justification required to fill the line, and it is shown and described herein merely as a representative of a type of machine possessing such capacities and adapted to cooperate with the novel features about to be explained.

No provision has thus far been made for the justification-perforations or those for establishing the dimensions of the space-type occurring in the line. In some forms of casting-machines a single set of perforations is or may be employed for setting the justifying mechanism, usually one for designating justification and the other for measuring the degree, but in the preferred machine (that of Patent No. 625,998) two such sets of perforations are employed for designating the individual justification-wedges and determining their position of adjustment; but no matter which arrangement is adopted the justification-perforations occupy the same position with respect to the character-perforationsthat is, at the beginning of the line of composition as set up in the casting-machine. Heretofore it has been customary to locate justification at the end of the line, necessitating the reversal of the record-strip and the setting up of the type in the reverse order of composition and rendering it impracticable to deliver the record-strip as composed di-- rectly to the casting-machine. According to the present invention these obstacles have been overcome by the provision of a second or separate series of punches, locating them at a point in rear of the character-punchesthat is, between the latter and the castingmachine and providing a feeding mechanism competent to present the space at the beginning of the line of character-perforations in position to receive the justification-punches after the series of character-perforations for the line have been produced. A form of mechanism embodying these features is shown in the drawings and will now be described.

.Supported in guides in rear of the character-punches 181 is a second series of punches 200. (Best seen in Fig. 26.) As applied to this particular machine there are seventeen punches in this series, of which fifteen correspond in position with the character-punches designating size-that is, the fifteen degrees of motion of the die-case in one direction-- while the other two, designating the justification-wedges, occupy independent positions. The equipment of the punches 200 is similar to that of the character-punches, although the punch-bars 201 are longer, to connect with levers 202, located beneath the level of the operating-bars 180. The levers 202 (best shown in Fig. 1 by dotted lines, the main portion being broken away to uncover the rest of the mechanism) are centrally pivoted at 203 and extend across the machine to a series of pistons 204, one for each lever. The pistons 204: are substantially the same as those which operate the indicating devices and characterpunches, but reversed in position, as shown in Fig. 15, so that their stroke is downward instead of upward. The application of pressure to each of these pistons is controlled by a valved key 205, working in a pressure-chamber after the manner of the character-keys. This provides a pneumatic action for the justification-punches; but it is obvious that they might be mechanically or otherwise connected to the keys for action. Each of the series of keys 205, termed justification-keys, is aption-wedges, and the balance bear'figures 6 to 20, inclusive, designating the series of positions of adjustment of the wedges.

In order that the same feed-valve 184 may be utilized for the justification-punches, a

rocking bar 206, Figs. 5, 6,26, and 29,

wheels are furnished with a series of equally spaced radial punches 212, and on an axis parallel with shaft 210 is a drum 213, containing radial perforations or dies 214, registering with the punches on wheels 211. Punches 212 serve not only to feed or carry the recordstrip past the character-punches by theirengagement with the holes in the margins of the strip, but, actingin conjunction with the drum 213, they operate to form the said marginal feeding-perforations, the paper as it is drawn from the supply-spool 216 passing first through a tension device 217, composed in this instance of two parallel rods, and then between the punch-cylinders 211 and drum 213, where the marginal holes are formed and the strip forced onto the punches, which thus become carrying-pins. Parallel with shaft 210 is a second shaft 220, provided with pinwheels 221 opposite the ends of the die of the justification-puuches, and between the two paper-feeding devices is arranged a stripper 222, beneath which the record-strip passes. After leaving pin-wheels 221 the record-strip is conducted over or through a guide 223, mounted upon pivoted arms 224, the latter carrying a set-screw 225, contacting with the frame for adjustment and held to position by a spring 226.

The character-feed is provided with an independent intermitting driving mechanism controlled, primarily, from the characterkeys, but responding also to the justificationkeys. Suchadriving mechanismis illustrated in the drawings, wherein the shaft 210 is provided with reversed ratchet-Wheels 227 228. The paper -feed operating rod 186, whose movements, it will be remembered,.are controlled by the valve 184, actuated by rocking bars 182 and 206, pertaining to the character and justification punches, is connected to one arm of a three-armed lever 229, the latter bearing a feed-pawl 230 on one arm and a pin 231 on the other for engagement with a stoppawl 232. Stop-pawl 232 engages one ratchetwheel 228 and feed-pawl 230 and holding-- pawl 233, the other after the manner of the single paper-feed mechanism of Patent No. 654,115.

The justification-feed is provided with an independent intermitting driving mechanism, also under the control of the character and justification keys, but differing from that, of the character-feed in that it is provided with means for withdrawing the stop-pawl and has cooperating with it a look-out for arresting the feed movement. In the example given there is secured to shaft 220 on the side of the frame opposite that on which the character-feed-driving mechanism is located two reversed ratchet-wheels 240 241. The holding-pawl 242 and the feed-pawl 243 engage one ratchet-wheel 240, while'a lockingpawl engages the other, 241. Feed-pawl 243 is carried by alever 244, pivotally supported on the shaft 220 and provided with a pin 245 for engagement with the locking-pawl, and said lever is actuated through the medium of a rod 246, connected to a piston 247,Fig. 28, the opposite ends of' whose cylinder is connected to the feed-valve 1840f the characterfeed, so that-pressure will be applied to the pistons of the two feed mechanisms simultaneously. The locking-pawl of the justification-feed is composed of two sections 248 249, (see Figs. 17 and 19,) pivotally connected and provided with abutting surfaces and a holding-spring 250. So far as the action of pin 245 is concerned in effecting the engagement of section 248 with the ratchet-wheel the twopart holding-pawl is rigid; but when itis desired to withdraw section 248, and thereby permit shaft 220 to rotate forward, it can be done by applying pressure to the tail of section 248 in a direction to separate the abutting shoulders and extend spring 250,. The purpose of this will presently appear.

It is apparentthat the two series of punches with their individual feeds working in unison are incompetent to effect the proper location of the justification at the beginning of each line, notwithstanding the placing of the justification-punches in rear of the characterpunches, except under one improbable condition-that is, when every linecontains exactly the same number of characters and the space intervening between the two sets of punches, measured in feed movements, corresponds with the number of characters in the linefor under such conditions the punching of the line characters would just bring the space at the beginning of the line opposite the justification -punches, and the operation of the latter would effect an advance movement sufficient to reserve a blank space at the beginning of the next succeeding line; but inasmuch as these conditionsseldom, if ever,oocur in practice, both the number of typein the line and the length of line being subject to variation, provision has been made for delaying or temporarily suspending theaction IIO of the justification-feed while all characterperforations in excess of apredetermined number are being produced, restoring its action when justification-perforations are produced and taking up the surplus record-strip after the last-named operation to reestablish initial conditions. \Vith these ends in view the justification-feed is provided with a lockout, represented in the present instance by the lock-bar 260, Figs. 16 and 18, movable in guides toward and from a toothed wheel 261, fast on the shaft 220 of the justification-feed. This lock-bar is provided with an intermittent feed device for advancing it toward the toothed wheel 261 and is located as many degrees of feed movement distant from said wheel as there are such movements contained in the predetermined standard, which latter is, say, fifteen degrees of feed or the number of feed movements required to advance the paper strip from the character to the justification punches, as determined by the length of feed and the distance between the feedshafts 210 and 220. The feed device or controller for lock-bar 260 comprises a ratchet mechanism similar to that of the characterfeed and is connected to operate in unison with the formerthat is to say, it includes reversed ratchet-wheels 262 263, holding-pawl 264, locking-pawl 265, and three-armed lever 266, connected by a link to the lever 229 of the justification-feed and carrying-pin 267 and feed-pawl 268. The lever 266 is pivotally supported upon a sleeve 269, Fig. 23, loose on shaft 220, said sleeve carrying in addition to the reversed ratchet-wheels 262 263 a toothed wheel 270, engaging a vertical rackbar 271, Figs. 16 and 20. This rack-bar is furnished with a shoulder 79 above and in the path of a projecting arm 272 on lock-bar 260, the latter being raised by a spring 273, engaging a rod 274, carrying guide 275 and adjustably attached to said lock-bar, Fig. 18. The arrangement of the connected driving mechanisms for the character-feed and lockbar is such that when the actuating-pawl of the former is retracted preliminary to a feed movement the actuating-pawl of the lock-bar mechanism will be advanced, and vice versa, the two having their operating strokes in sue cession, so that when the feed-pawl of the character-feed is retracted from the normal position (represented in Fig. 16) preliminary to its feeding stroke the rack-bar 271 will be raised one degree. It is clear, therefore, that upon the completion of any predetermined number of strokes of the character-feed the lock-bar 260 may be brought into engagement with wheel 261, thereby locking the latter and the justification-feed against motion. The withdrawal of the lock-bar from engagement with the wheel 261 is requisite to permit the justification-feed to move when the justification-punches are actuated, and provision is lnade for effecting such withdrawal whenever a justification-key is depressed.

Mounted in bearings within the casing is a shaft 280, Figs. 6, 26, and 27, and upon this shaft is loosely supported a bell-crank lever ceases 281, one arm of which stands above but in the path traversed by a projection 282 on rod 274, engaging the lock-bar, while the other arm bears against an arm 283, carried by shaft 207 of the rocking-bar 206 for the justification-punches. engagement with the Wheel 261, the projection 282 is nearly if not quite in contact with the arm of bell-crank 281, (shown in dotted lines, Fig. 27,) so that whenever a justification-key is operated and the rocking-bar 206 elevated the arm 283 will through its engagement with the bell-crank 281 draw the lockbar down against the resistance of its spring, thereby unlocking the justification-feed and permitting it to be operated.

In connection with the take-up it becomes desirable that the lock-bar when retracted or withdrawn by the action of the justificationkeys should be held out of action until the resetting of the indicating mechanism is accomplished, and this result is secured by the employment of a pivoted latch 284:, Fig. 27, provided with a shoulder 285 in position to engage a projection 286 on bell-crank 281 when the latter is moved by arm 283 to withdraw the lock-bar.

By suspending the justification-feed and continuing the character-feed in action a loop will be formed in the strip between the two feeds, the length of said loop being equal to the whole series of feed movements minus those participated in by the justification-feed, and as the latter is active only so long as is necessary to bridge the interval between the two feeds (say fifteen feed movements) plus the number required for justification, (say two,) it follows that in order to reestablish initial conditions the strip must be shifted with respect to the justification-feed a distance equal to this excess of motion on the part of the character-feed resulting in the formation of the loop-say seventeen. This function is performed by the take-up and is in the present instance participated in by the rack-bar 271, which latter, it will be remembered, is advanced or raised one degree each time the character-feed is operated.

Secured to the shaft 220 of the justification- WVhen the lock-bar is in feed is a ratchet-wheel 290, and in proximity I thereto, but loose upon said shaft, is a disk 291, carrying a spring-pressed pawl 292, engaging the teeth of the ratchet-wheel. The disk 291 is slotted for the reception of a pin 293, Figs. 23, 24, carried by the rack-engaging wheel 270. The length of this slot in disk 291 is proportionally equal to the predetermined number of feed movements-say seventeenperformed by the two feeds acting in unison, so that the movement of the driving-member wheel 270 in either direction will exceed that of the driven-member disk 290 in the same degree that the total number of movements of the character feed exceeds those of the justification-feed. Normally the pin 293 occupies a position at one end of the slot, as shown in Fig. 24, and in order to rethe line has been completed and the justification-perforations inserted at the beginning thereof, and this is accomplished by and during the return motion of rack-bar 271 after its elevation in the manner described. As the rack-bar is upheld by the feeding and hold-- ing pawls 268 and 264 of its ratchet mechanism, the withdrawal of said pawls, together with section 248 of the locking-pawl of the justification-feed, will permit the descent of said rack-bar either under the influence of gravity alone or, preferably, of a motor 290,

Fig. 16, thereby reversing the motion of wheel 270. During this return motion of the wheel its pin 293 traverses the slot in disk 291 without communicating motion to the latter until it contacts with the end of the slot, thereby, in effect, suppressinga number of the feed movements equal to the number of simultaneous movements of the character and justification feeds communicated to the rack-bar during its elevation. The continued movement of the gear-Wheel will thereafter be communicated to the disk and transmitted by the latter to the shaft 220, thereby causing the justification-feed to take up the slack in the strip, and thus reestablish initial conditions.

The tripping of the pawls 268, 264, and 248 is preferably automatically effected simultaneously with the resetting of the indicating devices, to which end the following arrangement of parts is provided. The tail of feedpawl 268 project-sbeneath the tail of holdingpawl 264, Fig. 16, in position to engage the latter when the former is elevated by a rod 297, mounted in guides onthe frameand engaging an arm 298, secured to shaft 280, Figs. 26, 27. Another arm299 on shaft 280 engages a rod 300, Whose upper end. is inposition to engage the tail of section 248 of the lockingpawl. Shaft 280 is also provided with an arm 301, Figs. 6 and 26, in position to engage an arm 302, attached to latch 284, when said shaft is turned in a direction to raise the disengaging-rods 297 and 300, whereby the'latch will be raised from contact with the pin on bell-crank 281, permitting the latter to be restored by its spring to initial position. The rocking of shaft 280 is produced through the agency of a piston connected to an arm 303 on said shaft and working in a cylinder 304 in communication with the resetting-motor 48 of the indicating mechanism, so thatwhen the resetting-key is depressed both shafts44 and 280 will be turned in their bearings. A spring 305 serves to return the shaft after the pressure in the cylinder iscut off.

As before mentioned, the rack-bar27l i preferably provided with a motor 296 to effeet and regulate its movement in taking up slack. The motor shown comprises a piston 306, connected to the rack-bar and working in a cylinder 307. Pressure is admitted to this cylinder above the piston through a duct 308,

communicating with the cylinder of theresetting-motor 41 or to the supply-pipe leading thereto at a point beyond theone-way throttlingvalve, so that the admission of pressure to the resetting-motor will also admit pressure to the motor of the take-up.

It only remains to describe the speed-control connection, whose principal function is to render the casting-machine responsive to a diminution in the quantity of record-strip supplied by the keyboard, thereby avoiding the necessity forand the evils incident to an attempt to synchronize those mechanisms.

It is obvious that the kind and character of the control mechanism will depend largely upon special conditions, such as the kind of motor and the means adopted for effecting control, and in the present instance an embodiment of the principle is. illustrated in connection with an electric motor 310, Fig. 2, for driving the casting mechanism, conventional figures being employed for the-purpose. To the motor is connected a rheostat orspeedcontrolling device or apparatus 311, Figs.2

and 12, of any known or approved form and construction, that shown being provided with a movable switch-arm 312, arrangedto engage successively each of a series of contacts 313 for regulating the speed of the motor by varying the resistance either of the main or a shunt circuit. I 1

Intermediate the justification and castingmachine feedsand in position to engage the record-strip extendingfrom one to the other is a roller 314, Figs. 1 and 26, supported on arms 315, attached to a shaft 316,-the. latter provided with a crank-arm 317, to whichis attached one end of a link318,.whose opposite end is connected to a crank-arm on shaft 319. This shaft 319 is provided with two slotted crank-arms, the. one, 320, engaging a pin on the switch-arm 312 and the other, 321, connected to a dash-pot 322. Whenthe parts are in normal operative position, the recordstrip depends in a loop. between the justification and casting-machine feeds, as indicated in Fig. 26, the roller 314 being in its lowermost position and supported by the contact of its carrying-armswith suitable hearings on the frame, while the switch-arrn312 engages a contact at one extreme of the series 313, said contact representing maximum speed of the casting-machine. So lon gas the loop of material beneath roller 314 ismaintained at or above a minimum amount, which latter is determined by therangular relation of the roller to the two feeds themaxim-um speed of the castingmachine will be preserved; but should the rate of supply at the keyboard mechanism fall below the consumption at the casting-machine the roller 314wi1l be displaced, thereby shifting the switch-arm or other speed-controlling media to cut down the speed of the casting-machine, relieving the the production of type, and with the assurance that if detained for a longer interval the casing-machine will automatically be slowed down and finally brought to a standstill without rupturing the record-strip or disturbing the feeding devices of the keyboard. This is an important point, for should the position of the recordstrip be changed either at the justification-feed or at the character-feed it would result in the production of a false record affecting one or two lines and the loss at the casting-machine ofacorresponding period of time and material.

The operation of the machine as a whole may be briefly summarized as follows: In starting up the machine the end of the strip is reduced in width, so that it can be threaded through the tension device 217 and conducted beyond the engaging members of the character and justification feeds, after which one or more keys of the keyboard are actuated a number of times to initiate the formation of marginal feeding perforations and efiect engagement and register of the strip with the pin-wheels of the two feeding mechanisms. The resetting-key being now actuated it restores the various mechanisms to their normal or initial positions, and the apparatus is in condition for operation. The keys representing the characters, spaces, the of a line are successively actuated in the order in which the type occur in composition, and as the end of the line is reached the operator, observing the justification indication, actuates the appropriate or designated justification-keys, then presses the resetting-key to restore the line-indicator and justification-indicator to zero and proceeds with the composition of the next succeedingline. The depression of each character-key and the elevation of its punch or punches admits pressure to the cylinders connected to the actuating-rods 186 and 246 of the character and justification feeds, thereby retracting the feeding-pawls preliminary to the feed movements, the latter taking place upon the return of the key. Coincident with the retraction of the two feeding-pawls the take-up rack 271 and the cut-out 260 are advanced one degree or measure. This doublefeed action and advance of the cut-out and take-up is repeated for each character-key until the predetermined numbersay fifteenhave been depressed, at which time the cut-out 260 will be brought into engagement with wheel 261 on shaft 220, thereby arresting the justification-feed with the first characbe actuated to advance the strip.

ter-perforation for the line two feed-measures distant from the justification-punchesthat is, with the space for the first justification perforations opposite the justificationpunches. The successive depression of subsequent character-keys actuates the charac ter feed and take-up, as before, causing the record-strip to be suspended in a loop between the two feeds. When the line is completed and the key is depressed to actuate the justification-punches, the rocking bar 206, overlying the justification-punch levers, acting through arm 23S and lever 281, withdraws the look-out 260, so that both feeds will again This double feed also takes place when the second justification-signal is formed, thereby completing the record for a single line, with the jus tification perforations or signals for the entire line located in advance of the character signals or perforations, the look-out being restrained by latch 284. The resetting-key is now actuated to admit pressure to the resetting-cylinder 41 and return the indicators to zero preparatory to composing the next line. \Vhen this takes place, pressure is admitted to cylinder 304, thereby effecting an oscillation of the trip-shaft 280, resulting in the withdrawal of the locking-pawl 248 of the justification-feed, thus rendering the latter free to advance, and the withdrawal of the actuating and holding pawls 268 and 264C of the takeup-advancing mechanism leaving the latter free to be returned to initial position. At the same time pressure is admitted to cylinder 307 to eifect the return of the take-up rack 271. During the return of said take-up it operates, through pin 293, slotted pawl-disk 291,and ratchet-wheel 290, to advance the justification-feed shaft through the whole number of degrees of feed movement applied to the take-up during the composition of the line less the number performed by the character and justification feeds when acting in concert. Thus in the example given the action of the take-up will equal the whole number of feeds performed by the character-feed less seventeen, the latter number representing the interval between the two sets of punches, together with the two feed movements incident to justification, for which allowance is made in the slot-and-pin connection 291 293, with the result that the surplus strip between the two feeds is taken up and the strip drawn taut, with the portion above the justificationpunches seventeen degrees of feed movement distant from the character-punches. As the look-out engages at the fifteenth feed movement, the justification-feed will be suspended when the second section in advance of that above the character-punches arrives above the justification-punches, and as the two sections beyond the character-pu nches are blank, having passed said punches while thej ustification-punches for the preceding line were acting, this brings the strip in proper position for locating the justiiication-perforations in these two blank sectionswhen the justification-keys are manipulated.
